I am pulling my hair out trying to figure out why I keep getting the 0301 code (misfire cylinder 1) has anyone else had this problem and what fixed it? I have replaced all spark plugs, injectors, MAF, TPS, coils, fuel filter, vacuum lines, etc Please help!!!!!
Is the wire routed around something that could be interfering with the voltage going through it? I know on my wife's Jeep, there was a TSB to re-route the wires if you had any misfire codes come up, and it involved only crossing other spark plug wires at 90 degree angles, no wires running parallel within a 3/4" of each other, etc.
